APPENDIX User Interface Specifications
This appendix describes the user interface specifications of the adapter board.
■User Interface Specifications
Figure A-1 shows the correspondence between the pin numbers of flat cable connectors A and B of the adapter board and those of the header or user system. Table A-1 and table A-2 lists the pinouts of flat cable connectors A and B and the evaluation MCU.
Note that the evaluation MCU signal names in the table are tentative names and their actual signal names vary with each model. The actual evaluation MCU signal names can be judged from the eval- uation MCU pin numbers. For details, Please ask, when unknown.
Each signal name of the evaluation MCU has the following meaning. See the notes that follow as well.
•Vcc_A : Internal power supply of the evaluation MCU (or the C pin).
•Vcc_B : I/O power supply of the evaluation MCU (or a single power supply).
• VCCXTL | : Main clock power supply of the evaluation MCU. |
• GND | : Ground of the evaluation MCU. |
Note : To the pins whose evaluation MCU signal name is underlined in the table, an additional circuit may be added for controlling the evaluation MCU. Therefore, those pins have different electrical characteristics from those on the actual MCU.
See the sections listed below for details on the additional circuit for each signal.
• P65/P85/PD3/PF2(DVcc) | : See Section 4.5 | "Installing a Bypass Capacitor for DVCC." |
• X0/X1 | : See Section 5.2 | "Setup for Clock Supply." |
• X0A/X1A(PF5/PF6) | : See Section 5.2 | "Setup for Clock Supply." |
• P54(RDX) | : See Section 5.4 | "Setup for |

The emulator uses Vcc_A and Vcc_B mainly as the power supplies to the evaluation MCU and addi- tionally for voltage detection purposes only; it does not contain circuit consuming large power.
It is advisable to use the flat cable (standard) bundled with the emulator to prevent noise trouble. Provide the user system with a connector equivalent to the flat cable connector. The part number of the flat cable connector is as follows:
•Flat cable connector part number:
Notice that the pinouts of flat cable connectors A and B are different between the adapter board and the user system.
